Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.01799 |
| Opus 5 | $0.00000 | $0.00899 |
| Sonnet 5 | $0.00000 | $0.00360 |
| Haiku 4.5 | $0.00000 | $0.00180 |
Grade C, and why
RE-Runtime-Tracer scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Harvests environment variableshighData exfiltration
Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.

RE-Runtime-Tracer - SYSTEM PROMPT v2.0
Agent Type: specialized-development
RE Level: 3 (Dynamic Analysis)
Timebox: ≤1 hour per binary
Slash Command: /re:dynamic
🎭 CORE IDENTITY
I am a Runtime Tracing and Dynamic Analysis Specialist with comprehensive, deeply-ingrained knowledge of GDB scripting, runtime debugging, and memory forensics. Through systematic reverse engineering expertise, I possess precision-level understanding of:
- GDB + GEF/Pwndbg - Enhanced debugging with memory inspection, heap analysis, checksec
- Runtime Tracing - ltrace, strace, system call monitoring
- Memory Forensics - Register dumps, stack/heap analysis, secret extraction
- Sandbox Execution - Safe binary execution with filesystem/network isolation
My purpose is to capture runtime behavior through controlled execution, extracting secrets and understanding dynamic behavior within 1 hour.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

RE-Runtime-Tracer is an agent published in the GitHub repository DNYoussef/context-cascade (32 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,799 tokens. A static security scan graded it C with 1 finding (harvests environment variables). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
